Add more Proxy Types

[tnkshuuhei]

Description

First of all, I think it's great that added Proxy to Shibuya! Then in addition to "Any", how about adding at least the following Proxy Types as implemented in Kusama?

• Non-transfer
• Governance
• Staking
• Cancel https://github.com/AstarNetwork/Astar/blob/6fe8d30b80f621aff6447e1eeda0532f554bd668/runtime/shibuya/src/lib.rs#L967-L969

Why do we need?

As explained in the Polkadot wiki, "Any" is not secure. https://wiki.polkadot.network/docs/learn-proxies

Of course, there are very few cases where Proxy accounts are used in the entire Polkadot ecosystem. However, the idea of making good use of Proxy accounts to create secure Defi and Wallet could come from the ecosystem and help protect users(IMO).

Thank you

Thank you so much for the suggestion. Demand-based runtime improvements would be good. Since we don't have node staking, I'd like to suggest to go with Non-transfer, Governance, Cancel in Shibuya first

@shunsukew Very nice. I believe it would be great for community

@tnkshuuhei Having only Any is not practical, adding basic types like NonTransfer and Cancel would be good regardless of whether we get feature requests directly from someone based on demands for actual usage in my opinion. If such proxy types are available, someone would like to make use of them. Do you have any use cases or situations where you need these proxy types, especially Governance?

[tnkshuuhei]

As for governance proxy, it depends on whether AstarNetwork implements on-chain governance.

Cancel Proxy may be necessary if implement a Time delayed proxy. For example, with these, we could create accounts that are resistant to hacking. (In some cases, you might use Multi-sig together, though...).

Furthermore, we might be able to develop a highly secure wallet like Argent by using it with Recovery pallet, without having to implement smart contracts. In fact, most of chains don't implement contract pallets in polkadot. but the entire polkadot ecosystem can use the wallet simply by implementing pallets in the runtime.

These ideas are just the tip of the iceberg.

To be honest, I think the use cases for proxy are only going to increase, and there are very few Dapps that support proxy.The polkadot js UI does not support complex proxy.

PR merged and described proxy types will be added to Shibuya with the next runtime upgrade. DappsStaking proxy type is also added.
